Electrical impedance scanning imaging detection probe with pressure sensitivity

Abstract

The invention discloses an electrical impedance scanning imaging detection electrode probe with pressure sensitivity. The probe comprises a detection electrode array plane, a pressure detection device and a pressure detection processing circuit, wherein force sensors are arranged on the pressure detection device; the pressure detection device is placed below the detection electrode array plane and is directly or indirectly connected with the detection electrode array plane; the pressure detection processing circuit comprises a pressure signal input interface, a signal conditioning module, an A / D (analog to digital) conversion module, a microprocessor module and a pressure indication output module. The probe aims to carry out pressure sensitive detection on the operator and has the following characteristics: the pressure and pressure uniformity prompts can be given while detecting the target position, thus being beneficial to keeping good contact between the detection electrode array and the position to be detected during operation and reducing dependence on operation experience.

Description

technical field [0001] The invention relates to an electrical impedance information detection probe, in particular to an electrical impedance scanning imaging detection probe with pressure sensitive characteristics. Background technique [0002] Electrical impedance scanning detection imaging systems mostly use flat-panel multi-unit array detection probes to scan and detect superficial organs of the human body (such as breasts and lymph nodes under the armpit). During the detection, the operator holds the detection probe and places it on the surface of the measured part. The electrode unit array on the detection probe is used to sense the current signal. The electrical impedance distribution of the tissue. In order to ensure the close contact between the electrode array unit and the skin, the operator needs to use a certain force to press the detection electrode plane smoothly on the detection site during detection, and the degree of force needs to be maintained until one s...
